This four-wave longitudinal study among 698 Chinese early adolescents explored (1) how personal identity coherence and confusion develop; and (2) whether parenting style and peer relationships (i.e., close friend relationships and peer preference) were related to personal identity development. Participants (M[subscript age] = 11.39 yrs.,…

Although school climate plays an important role in the development of adolescent prosocial behaviors and problem behaviors, little is known about the mechanisms underlying school climate's impact on such behaviors, particularly in Chinese adolescents. This study used a multi-informant approach to investigate the mediating role of social-emotional…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

The present study examined influences of sixth-grade student-reported parent educational involvement on early adolescent peer group affiliations at seventh and eighth grade. In addition, student gender and ethnicity were explored as possible moderators. Drawn from a large effectiveness trial, participants in this study were 5,802 early adolescents…

This study evaluated a brief social self-efficacy (SSE) measure among 4,122 public middle school adolescents and its association with aggressive behavior. Data analytic procedures included calculating mean ratings, standard deviations in addition to inspecting the scale's reliability, internal structure, and relationships to demographic and…

A systematic review was conducted on the role of substance use initiation in subsequent use and substance-related problems among adolescents. Specifically, we examine previous studies to identify whether age of onset predicts subsequent levels of misuse; we also posit reasons for this association that have been suggested within the literature. In…

Introduction: Based on internal and external assets, the positive youth development approach aims to increase the capacity among adolescents to overcome challenges as they transition to adulthood. Developmental assets have been found to be positively associated with academic achievement, a variety of health promoting behaviors, and improved…

We used self-report surveys to gather information on a broad set of non-cognitive skills from 1,368 eighth graders. At the student level, scales measuring conscientiousness, self-control, grit, and growth mindset are positively correlated with attendance, behavior, and test-score gains between fourth grade and eighth grade. Conscientiousness,…

Recent advances in positive youth development theory and research explicate complex associations between adaptive functioning and risk behavior, acknowledging that high levels of both co-occur in the lives of some adolescents. However, evidence on nuanced overlapping developmental trajectories of adaptive functioning and risk has been limited to 1…

New analytical tools have facilitated the exploration of the trajectories of alcohol use; however, there are a limited number of studies that explore early adolescence. A sample of 5,903 youths followed from sixth through eighth grade was used to (1) examine the trajectories of alcohol use and (2) determine the degree to which common correlates…

The purpose of this replication study was to examine the relationships among life satisfaction, positive youth development and problem behaviour. The respondents were 7,151 Chinese Secondary 2 (Grade 8) students (3,707 boys and 3,014 girls) recruited from 44 schools in Hong Kong. Validated assessment tools measuring positive youth development,…

This research examines the relationship between career related self-concept and dimensions of informal learning of science. The overlapping dimensions of career interest development and informal learning suggest that self-directed informal learning of science can advance individual self-concept for "possible scientific self." Possible…

This mixed-methods longitudinal project investigates the association between student perceptions of their schools and themselves. Findings from the first two waves of data analysis with 894 middle and high school students in a midsized Great Lakes city reveal similarities and differences between the grade levels (7th-10th) and their perceptions of…

Communities are critical arenas for adolescent development. This study uses mixed methods to assess contextual correlates to community connectedness in 8th, 10th, and 12th grade youth. The survey examined the relationship between community connectedness and four developmental supports: safety, community monitoring, creative outlets, and meaningful…

Does success in school protect teenagers from drug use? Does drug use impair scholastic success? This book tackles a key issue in adolescent development and health--the education-drug use connection. The authors examine the links and likely causal connections between educational experiences, delinquent behavior, and adolescent use of tobacco,…
